ABSTRACT

The present study reports the distribution of ABO and Rh blood groups among the Kunbis

(Maratha) population of Amravati district. The phenotypic frequency of blood group B is observed

highest (33.06) percent, O (31.04), A (27.02) and AB is lowest (08.33) percent. The phenotypic

frequency of Rh negative is (04.26) percent. TheKunbis (Maratha) population shows close genetic

relationship with the Gujratis.

INTRODUCTION

In the present paper, we studied the distribution of ABO and Rh blood group among the Kunbis

(Maratha) population of Amravati district, Maharashtra. Kunbi was claimed to have been warriors

and land lord having their roots in Maharashtra. They belong to the Hindu cast and are considered

Nature Precedings : doi:10.1038/npre.2010.4868.1 Posted 8 Sep 2010 as close to the upper class from the same geographical location. One rung of the ladder of

social advancement is to provide oneself with origins. Kunbi are widely distributed in

different parts other than Maharashtra, are , , and . They

speak the Marathi, one of the major languages of Indo-Aryan language group. The Kunbis

number 193,255 or 24 per cent, of the population (Census of India 2001). They are 4

overwhelmingly the most important in the district, and the Kunbi has come to be the accepted

type of all Maratha cultivators.

MATERIAL AND METHODS

1500 blood samples are collected in to EDTA vials from different Kunbis residing areas of

Amravati district. All samples are tested for the ABO and Rh blood groups using anti - A,

anti -B and anti - D sera. Gene frequencies are calculated by Hardy-Weinberg principle using the

WinBug program (Spiegelhalter, et al., 2003).

RESULTS AND DISCUSSION

The distribution of the ABO and Rh blood groups among the Kunbis population of Amravati

district is shown in the table 1. Blood group B predominates in distribution with the highest

Nature Precedings : doi:10.1038/npre.2010.4868.1 Posted 8 Sep 2010 frequency (33.06%) fallowed by blood group O (31.04%) and blood group A (27.02%). The

frequency of allele B is quite high (0.2354) as compared to A (0.1978). The frequency of Rh

negative is (d = 0.2065).

Roychoudhury (1977a) used smaller number of genetic loci and observed the genetic relationship

of Kunbi (Maratha) and Gujratis which is closer to each other than to the Hindus of Madhya

Pradesh. 5 Nature Precedings : doi:10.1038/npre.2010.4868.1 Posted 8 Sep 2010 6
